Currently, the hoodie is out of stock, but you can see it with its multicolored LEDs and soundbox in action below:

The makers have come up with light and sound combinations for nine different spells, including thunderbolt, fireball, restore health, and raise the dead, although it comes with the following warning:

The Technomancer isn't for everyone. You'll need to spend some time mastering the various spell effects. Each spell requires different motions. The way you wear the garment and how precise your movements are will greatly affect your results. Don't expect to become a master wizard the second you open the box. Time and patience will be your guide to unlocking the power of the Technomancer. Impatient sorcerer's apprentices should not apply.
